Tent and pumpio are both kind of failed projects that still have good ideas worth salvaging, IMO.  Though pumpio might be coming around which is nice.

@maiyannah pump.io is a very neat idea. Wish it had a bigger following tbh

@hyper They shot themselves in the foot taking identi.ca the way they did and forcibly defederating it from the existing OStatus network to try to force adoption of the new standard.    and it hasn't recovered from the negative reaction, to this day.

Kind of like Mastodon is talking about doing with ActivityPub, really.

We've seen this song and dance before and it's why I've no intention of playing along.

To be fair, the !StatusNet network that Evan was running became unmanageable -- it cost too much to run, and I think Evan was funding most of it himself (although there were/are a number of paying #StatusNet customers). Evan developed #PumpIO to reduce the number of servers needed to run a federated network, and purposely kept the UI to a minimum to encourage federation. Sadly, that didn't work. Porting identi.ca from StatusNet to PumpIO was intended to introduce people to PumpIO as well as reduce Evan's costs. That partly worked; identi.ca is alive and well as a community, although much reduced from its glory days around 2013. But the #bifurcation did spawn a large number of new StatusNet / !GNUsocial instances, so that was a good thing too. But you're right in that PumpIO never gained widespread traction, the proof of which is in its lack of continued development. In that respect #GNUsocial and !OStatus are more successful than PumpIO
